Question:

A portable photometer with a linear response to radiation registered 75.5 (A with a blank solution in the light path. Replacement of the blank with an absorbing solution yielded a response of 23.7 (A. Calculate
(a) The percent transmittance of the sample solution.
(b) The absorbance of the sample solution.
(c) The transmittance to be expected for a solution in which the concentration of the absorber is one third that of the original sample solution.
(d) The transmittance to be expected for a solution that has twice the concentration of the sample solution.
